Proposed the method for determining support stiffness, based on the use of mating parts surfaces interaction contact models. The calculation method of the pump rotor axial unloading unit - hydraulic balancing device. Obtained the formulas for calculating of energy loss in the cylindrical and face chokes of the hydraulic balancing device. Presented the torsional natural frequencies and mode shapes calculation methods focused on the use of computer algebra systems. Product Description popup.authors Бурий А.С. Дем'яненко М.М.
